Application filed. August 10,1907. Serial No. 387,936.

To all whom it may concern:

Be it known that I, HEZEKIAH L. TRUE- BLOOD, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain specification.

This invention relates. to a hand tool or implement that is designed to be used in performance of various operations for the purpose of keeping saws in roper working order which may be require as a result of their use, the invention having reference articularly to a combination tool having abilities for holding a file in different positions for truing the saW teeth and having also a saw set or device for setting the saw teeth, and. a double gage'to'be used for-determining the adjustments of the setting apparatus and combining also a swagefor the rake teeth of the saw.

The object of thein vention is to provide an improved combination tool of the abovementioned character that will enable a saw filer to carry on his work ex editiously and without requiring the hand ing of various separate tools or implements, a further object being to provide in one sim le and chea ly constructed tool certain eatures which heretofore'have been constructed as separate tools or implements that necessarily'involves relatively greater eX ense for material and labor, a still further 0 ject being. to rovide a compact, strong and eco nomica saw filers tool or implement.

With the abovementioned and minor objects inview the invention consists in an improved combination tool' provided with means for holding a file to be used as a saw-' jointer, the implement including a saw set of novel form and arrangement, a saw swage, and adjustable gage for the saw set, and a double standard test gage for regulating the amount of the set of the saw teeth; and the invention'consists further in the novel parts and combinations and arrangements of parts as hereinafter particularly described and pointed out in the ap ended claims.

Referring to the rawings Figure 1 is a plan view of the combination tool showing the side thereof on which the file is held thereby; Fig. 2, a plan view showing the opposite side of the tool; Fig. 3, a transverse sectional view on the line A in Fig. 2; Fi 4, a transverse sectional view on the line in Fig. 2; Fig. 5, a perspective view of a double clamping jaw for holding the file in different positions; and, Fig. 6, a perspective view of the adjustable stop gage of the saw set.

Similar reference characters in the different figures of the drawings designate like elements or features of construction. I

Combination tools have heretofore been made for holding jointing files in different positions, but in the construction thereof relatively expensive operations were reuired in order to produce-the devices for c amping the file, and in the present invention such difficulties have been obviated in an improved form of construction, and other features have been advantageously arranged as parts of the complete implement which comprises a body part a which may be composed of any suitable metal such as cast iron, the general shape of which is somewhat like a fiat plate suitably apertured to avoid excessive weight. One side ofthe body part in its incomplete form presents a flat surface, and

portions of the opposite side have two file seats I) and c on which a file may rest fiatwise, there being shoulders I) and c on the seats to be engaged by one edge of the file. The same side of the body part has suitable flanges d and (1 along its-edge joined to the file seats, and. also ribs 6 and e extending along the middle portionof the body part op osit'e to the flanges and also joined to the file seats.

The body part is provided with a pair of abutments f and f near the o posite edge thereof, and they roject from t esame side of the plate on w ich the ribs e and eare formed to assist in holding afile which may be placed flatwise against the abutments. A threaded nut g is fixed to the body part a andprojects from the side thereof between the ribs 6 and e. A double clamping jaw h is mounted on the side of the body part a and is suitably apertured to clearthe nut g and provided at one end thereof with a head h, the opposite end being adapted to engage and hold a file against the abutments) and j the head h being engaged by the head of a scFew body part as shown in Fig. 1 or flatwise as indicated by broken lines also in Fig. 1.

The portion of the body part a on which the abutmentsj and j are arranged also has two j and k that project beyond the edge of the body part at opposite end'.portions thereof and also a gage projection Z which is arranged between the other two projections but somewhat nearer to one than the other one, and the projection Z extends farther beyond the edge of the body part than the" other two projections, so that if two of the projections as and I be placed on a straight line or plane ma, the projection 7c will be at some distance from'the line, and if the projections Z and k be placed on the line, the projection j will be nearer to the line as in Fig. 2, than the rejection is would be to the line as indicate in Fig. 1. Said line may represent a side of alsaw, and if it be desired that the saw teeth are to have a considerable degree of set this may corres ond to the distance between the end of t e projection k and the side of the saw, or correspond to the line at n, and the test tooth is to be set over the projection j than it is to the projection is when using the setting tool.

and sulliciently long so that when on a plane either one of the projections 7' or It only can touch the same plane at one time.

A bar 0 which should be made of relatively, hard metal is secured by rivets p and p to the flat side of the body part a and is some what shorter than the body part, one end of the bar having a head I in which is a slot 1' to receive a saw tooth, the inner end of the slot having a reeessslbr clearance pur oses. The slot is adjacent to the side of the ody-part a which may serve as a guide against the tooth The opposite end of the bar 0 has a point t to be entered between two rake teeth and has two opposite eoncavely-curvml sides a and a, de signed to cause the teeth to bend slightly away each from the other, the adjacent side of the body )art a serving as a guide against the sides of the teeth while using the swaging tool. A stop gage c is arranged also on the flat side of the body part a adjacent to the bar owhich serves as a guide while adjusting the gage, the latter having a slot w therein through which extends a screw as that is threaded into the body part a, said gage having a contact end 12 adapted to engage the side of the saw when a tooth extends into the slot 1" and the tool is operated to set over the tooth. The file '3] indicates one of the well known ways in which the file may be used, and the file 2 shown by broken lines indicates the different positions for holding the avoid some of the work usually necessary in filing the rake teeth; When setting the teeth the head Q will be placed on a tooth which will extendinto the slot 1', and then the tooth' should be set over slightly and tested by either the gage y' or the gage k, as may be desired, and when it tests to the desired gage then the stop gage 1) should be adjusted so as to produce the requiredamount of set accordin to the standard test gage. In case that it be desired to deviate from the standard gages, the stop gage '0 may be further adjusted as may be required to obtain the amount of set that may be preferred. 7

Having thus described the invention, what is claimed as new is 1. In asaw set and swage, the combination with a bar having a slot in a side of one end thereof and a tapering point on the opposite end thereof, of a body part bearing against said bar and extending across one side of said slot and also at one side and beyond said point as guides to engage 'thesaw teeth.

2. In a saw set, the combination with a metal plate that has a long portion and a relatively short portion, of a bar of relatively hard metal that is secured rigidlyto a side of the long portion of said plate, one end of said bar having a head that extends beyond an end of said long portion and has a slot in a side. thereof extending to the long portion of said plate, one side of said bar being straight and serving as a guide part, a stop gage on the shorter portion of said plate and bearing against the guide part of said bar, said gage having a slot therein and also having a contact end extending beyond the shorter portion of said plate, and a binding screw extending through said slot and threaded into said plate.

In testimony whereof, I affix my signature in presence of two witnesses.
